Exclusive: Watch Lady Mary Break Bad in Good Behavior

After five years of playing buttoned-up Lady Mary on Downton Abbey, which ended in March, Michelle Dockery has shed her pearls and opera gloves to play a thief and con artist. This November, she'll star on TNT's new show Good Behavior as hot mess Letty Raines, a woman fresh out of prison who is attempting to get her life back in order (especially for the sake of her 10-year-old son), but gets involved in a dangerous relationship with an irresistible hitman. It's a thriller not to be missed based on our exclusive first look at the action-packed trailer, ahead:
